Description
BACKGROUND OF THE INVENTION Field of the Invention

This present invention relates to exercise devices that are simplistic in design and with few components, and are discreet, low impact, compact, portable, and wearable, for use in resistive isotonic and isometric exercises for sports conditioning, muscle development and physical rehabilitation of all major upper body and leg muscles. Such devices are designed for multi-planar exercises in lying, sitting, and standing positions.

Description of the Related Art

Human exercise motion can be defined in three dimensions by planes that dissect the body, the sagittal, frontal, and transverse planes, and axes of motion in these planes. The sagittal plane is vertical to the body and divides it in right and left halves. Examples of exercises in sagittal axis of motion are biceps curls and squats. The frontal plane is vertical to the body and divides it in front (anterior) and back (anterior) halves. Examples of exercises in the frontal axis of motion are star jumps, side bending, and lateral arms raises. The transverse plane is horizontal to the body, divides it at the midsection into top and bottom halves. Examples of exercises in the transverse axis are golf swinging or baseball throwing. Full body exercise routines should engage and move the muscles in the axes of motion of all three planes.

Isometric and isotonic are two types of resistance exercises. Isometric exercises are where the body muscle(s) remains still against a static force, and in isotonic resistance exercises the body muscles move against a resistance force. A combination of isometric and isotonic resistive exercises is used to condition and strengthen the major upper body and leg muscles.

Some isotonic resistance exercise techniques use free weights or exercise equipment with weights or bands (elastic or inelastic) that are bulky and expensive. Moreover, the exercise weights and machines may require maintenance or repair, and can cause muscle strain or bodily injury from over use or misuse. These exercise devices or their equivalents are heavy, not portable, and unwearable for discreet office or home exercise routines.

The above-cited art have harnesses, straps, bands (elastic or inelastic) or anchor points that may shift or break under load (force) during exercise, and potentially result in injury to the joints, tendons, ligaments, or muscles. These inventions are not discreet for office use, but rather are bulky, have large footprints and are slow to attach and detach from the body because of their cables, bands, and anchor device components. The attachment points of the exercise devices to the arms and legs limit their range of motion. The other inventions cited, with wrist or cuff attachments, are inexpensive to manufacture, small and portable, but limited in scope of exercise applications, and therefore, have limited range of exercise positions to engage and exercise all muscles in the upper body torso and leg muscles, or target all major muscle groups. These devices can't facilitate multi-planar exercises in the sagittal, transverse, and frontal exercises required for full body exercises. The exercise devices described in the above-listed references do not facilitate multi-planar full range of exercises, arm curls and extensions, side stretches and leg bends, arm curls with legs, leg sweeps, sit-ups and squats exercises that engage upper body and leg muscles for full body muscle strengthening and development.
